STOVE.

SPECIFICATION forming part of Letters Patent No. 402,451, dated April 30, 188.9.

T0 all whom it may concern:

Be it known that we, HERBERT HOPKINS and JOSEPH R. PERRY, citizens of the United States of America, residing at Wilkes-Barr, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Stoves, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention pertains to certain newand useful improvements in stoves; and it comprises the details of construction, combination, and arrangement of parts, substantially as hereinafter fully set forth, and particularly pointed out in the claims.V

In the accompanying drawing the figure is a vertical sectional view of our invention.

Referring to the drawing, A designates a stove; a, the hre-pot; and a the ash-pan.

B is a base-ring, having avertical iiange, b, into which are screwed the inner ends of airinlet pipes b', secured at their outer ends to the sides of the stove. These features are more fully described in an application for patent iled by us April 3, 1888, Patent No. 395,327.

O is a hot-water or steam pipe or cylinder, the lower tapering end of which is secured within the base-ring B by means of an outer collar, b, and an inner collar, el, fitted around the lower contracted portions of an inner smaller hot-air pipe or iue, E, the lower end of which rests on said base-ring. Apertures e are formed in this pipe or iue E for the passage of air therethrough. These pipes C E are united or4 held together by suitable means at or near their upper ends. A coldwater-supply'pipe, F, is passed down into pipe C to near the lower end thereof, and to the upper end or other suitable point of the hotwater or steam chamber formed by said pipe O is secured a steam or hot-water outlet pipe, f.

G is a blow-oi pipe screwed into apertures of the base-ring B and ring d, and fitted at its lower end with a cock or valve, as g, capable of being turned by a wrench or other suitable instrument to effect the blowing off of Application vfiled January 11, 1889. Serial No. 296,097. (No model.)

mud or other sediment in the hot-water or steam chamber.

A grate, H, is disposed above pipes h', and it has an outer rim, h, which rests upon said pipes, the inner end being supported by a flange of the base-ring B. A handle, h', for operating this grate, is projected through an opening in the stove.

By means of our present invention water in the pipe C is readily and quickly heated by the iire in the fire-pot and the hot air in pipe or flue E. The steam can be drawn from the upper end of pipe O and caused to pass through radiators, (not shown,) and the same can, when condensed, be returned to the water-supply pipe or to pipe O by a branch pipe, (also not shown,) or may return by steam- Pref- By tapering or` contracting the lower ends of pipes C E the same are made to occupy but a minimum amount of space in the repot. The same can be readily heated and the ashes will easily fall away from the side of the Water-pipe C by reason of the taper thereof.

It will be understood, of course, that chan ges within the scope of this invention can be made without departure from the spirit thereof in adapting the same to ranges or cookingstoves or for hot-air furnaces and steam-heating purposes. i

We claim as our inventionl. The combination, with the base-ring, of the hot-water or steam pipe or cylinder, the inner central hot-air pipe ,or flue, and the rings h and d, substantially as set forth.

2. The combination, with the base-ring and the air-inlet pipes, of the outer pipe or cylinder and the inner pipe or fine having a lower apertured end, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
